Mate, ditch Hathway if you can. In my building too there were many complaining about frequent drop in lines and are willing to jump if given the option. I got Airtel installed and its a breeze. Even the cable operator called my dad and asked why did you go for Airtel when we have the best service(hathway). Best, my ars*.
Even though Reliance is a majority share holder, I don't think its situation would improve in the immediate future as it will pose a direct challenge to Jio. Maybe when jio is well established in BB market would move things as a sidekick but untill then I don't see much improvements.
